Interactions between your drugs
testosterone nevirapine
Applies to: Testro-LA (testosterone), nevirapine
MONITOR: Coadministration with nevirapine may decrease the plasma concentrations and therapeutic efficacy of drugs that are substrates of CYP450 3A4. The proposed mechanism is increased clearance due to nevirapine-mediated induction of CYP450 3A4.
MANAGEMENT: Caution is advised if nevirapine is used concomitantly with drugs that are CYP450 3A4 substrates. Dosage adjustments as well as clinical and laboratory monitoring of coadministered drugs should be considered whenever nevirapine is added to or withdrawn from therapy.
